This deck is massively strong and can quickly bury your opponent in value
It's removal, buffs, evasion, and flavor, all rolled into one
Its possible, and a very minor part of its story, I guess
We already have a couple of enchantment decks built around cards like Hallowed Haunting that could easily run Invasion of Theros to tutor Heliod, the Radiant Dawn and Ossification and then flip into Ephara, which seems like a tough card to beat outside of a Farewell or Sunfall
It also helps that this is an Azorius precon, meaning it only uses white and blue mana, keeping things simple for new players, but the volume of colorless cards also means you should never be short of cards to play, so long as you have mana on the board
